Why is my teleport script not working?

So I wanted to make a script so when there are more then 0 players (I will later make it higher then 0) the game will start and everyone will be teleported to this location:

local GameRunning = false

if game.Players.NumPlayers > 0 and not GameRunning then
	GameRunning = true
	game.Players:GetPlayers().Character.Torso.CFrame = game.Workspace.LivingRoom.CFrame
else
	GameRunning = false
end

I believe that tables don't have Characters.

Let's see here.

You are using GetChildren() incorrectly, if you read the article I provided you with, it says

Returns an array of the object's children.

Now, what is that?

An array is basically a Table. You are trying to get a Character of a Table!

So that is what's wrong!

Now, if you dig deeper into the article, you'll see an example of how to use GetChildren().

for index, child in pairs(workspace:GetChildren()) do
    print(index, child.Name)
end

That is called a Generic For Loop, which loops through tables, like GetChildren().

So by combining the knowledge we got with this answer, we can now properly use GetChildren!

local GameRunning = false

if game.Players.NumPlayers > 0 and not GameRunning then
	GameRunning = true
	for i,Player in pairs(game.Players:GetPlayers()) do --Generic For Loop
		Player.Character.Torso.CFrame = game.Workspace.LivingRoom.CFrame
	end
else
	GameRunning = false
end

Now, we fixed this problem, but there's another one, you're only checking once!

Say you wanted a game to start if there were more than 1 person, then you wrote this

if game.Players.NumPlayers > 1 then
	--blah blah
end

That would check, but it'll only check once. The number of players to start is supposed to be 2+, but if I join, the script will check once, and it'll finish, so that won't work!

so what we can do is hook it up to the PlayerAdded event!

game.Players.PlayerAdded:connect(function(plr)
	if game.Players.NumPlayers > 1 then
		--blah blah
	end
end)

And there you go! If you use my scripts, in the future, you'll see some problems, but that is for you to sort out!
